ABSTRACT:
A bed plate for a fluid bed apparatus comprises a great plurality of bulges or dents each having at least one through-going gas flow opening defined therein. Conventional bed plates having openings of the gill type inevitably comprises small cracks or notches formed in the edge portion defining each of the gas flow openings. According to the invention the gas flow openings are formed in the bulges or dents in a manner so as to exclude the formation of such notches in the edge portion. This may, for example, be done by forming such openings with crack free edges prior to or after the formation of the bulges or dents. Thus, the openings may be formed by punching, drilling, laser cutting or the like. Each of the gas flow openings is directed in relation to the plane of the bed plate so as to cause a flow of gas, which is passed through the opening, to contact an adjacent part of the bed plate, which interconnects the bulges or dents.
